Abstract

A data generating apparatus includes: an input unit that receives foot shape data; a processor that computes shoe last data from the foot shape data received by the input unit; and an output unit that outputs the shoe last data computed by the processor. The processor further computes processing data for processing a member that forms an upper of a shoe, based on the computed shoe last data. The output unit further outputs the processing data computed by the processor.

First claim

an output unit that outputs the shoe last data computed by the computing unit, wherein
the computing unit further computes processing data for directly processing a member that forms an upper of the shoe from the computed shoe last data,
the output unit further outputs the processing data computed by the computing unit to cause a processing apparatus to process the member to form the upper of the shoe,
the input unit further receives information about the member that forms the upper,
the computing unit directly corrects the processing data from the received information about the member that forms the upper,
the member that forms the upper includes one or more sheet-shaped members, and
the processing data is cutting data for cutting at least one of the sheet-shaped members.

2. The data generating apparatus according to claim 1 , wherein
the shoe last data includes first data corresponding to an upper-side region of the shoe and second data corresponding to a sole-side region of the shoe.

3. The data generating apparatus according to claim 2 , wherein
the computing unit computes the processing data based on the first data.

4. The data generating apparatus according to claim 1 , wherein
when the member that forms the upper includes a plurality of the sheet-shaped members, the computing unit computes the cutting data for each of the sheet-shaped members.

5. The data generating apparatus according to claim 4 , wherein
the member that forms the upper includes the sheet-shaped members containing heat-shrinkable threads, and
the computing unit computes an assumed heat shrinkage coefficient of the threads contained in the sheet-shaped members, and corrects the cutting data based on a result of computation.

6. The data generating apparatus according to claim 5 , wherein
the computing unit computes information about a heating condition when the sheet-shaped members cut based on the cutting data are processed, and
the output unit further outputs the information about the heating condition computed by the computing unit.

7. A shoe manufacturing system comprising:
a measuring apparatus that measures foot shape data using a three-dimensional scanner or a mobile phone;
a data generating apparatus that generates shoe last data for manufacturing a shoe based on the foot shape data measured by the measuring apparatus;

a processing apparatus that processes a member that forms an upper, based on processing data generated by the data generating apparatus, wherein
the data generating apparatus includes:
an input unit that receives the foot shape data;
a computing unit that computes the shoe last data from the foot shape data received by the input unit; and
an output unit that outputs the shoe last data computed by the computing unit to the shoe last producing apparatus, wherein

the member that forms the upper includes one or more sheet-shaped members, and
the processing data is cutting data for cutting at least one of the sheet-shaped members.

8. A data generating method for generating shoe last data for manufacturing a shoe from measured foot shape data, the data generating method comprising:
receiving the foot shape data from a three-dimensional scanner or a mobile terminal;
receiving information about a member that forms an upper;
computing the shoe last data from the received foot shape data;
computing processing data for directly processing the member that forms the upper of the shoe from the computed shoe last data;
directly correcting the processing data from the received information about the member that forms the upper; and
outputting the computed shoe last data and the computed processing data to cause a processing apparatus to process the member to form the upper of the shoe, wherein
the member that forms the upper includes one or more sheet-shaped members, and
the processing data is cutting data for cutting at least one of the sheet-shaped members.
